Video-Assisted Modified Left Sympathectomy for Long-QT Syndrome

Abstract

A 22-year-old female suffering from idiopathic long-QT syndrome complicated by frequent syncope, torsade-de-pointes-type ventricular tachycardia, and asthma, was successfully treated by video-assisted extensive left second and third thoracic sympathetic ganglionectomy, instead of left stellate and first thoracic ganglio-nectomy, to avoid postoperative Horner's syndrome. The QT interval was significantly shortened from 0.6 to 0.43 seconds four days after the surgery. It remained at 0.43 seconds during a 3-month follow-up with no recurrence of tachycardia or syncope.
